Why would you want the people you hire to live with you? Beats me.

I would like a maid and gardener to come by as needed (once a week-ish). A chef is a great idea. I could hire him/her to cook 2 meals a day, 4 days a week and I'd be quite happy. I'd probably become a much better cook by doing so, as well, which would be a bonus.

A trainer would be total spew, because I'd hire them just to make fun of them.
